Description:

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention generally relates to an electrical connector,
and more particularly, to a novel structure of an electrical connector
with a baffled stick for restricting reverse of contacts.

[0003] 2. Description of Related Art

[0004] An electrical connector includes an insulative housing and a
plurality of contacts secured in receiving passageways of the insulative
housing in a direction from down to up. Each contact defines a contacting
portion protruding from a mating face of the insulative housing, an
elastic portion receiving in the receiving passageway and connecting with
the contacting portion and a retention portion retained in the receiving
passageway and extending from the elastic portion. In a process of the
electrical connector mating with a complementary connector, a lateral
pressing force is exerted on the contacting portions to making the
contacting portions move in a direction face to the mating face. The
pressing force is also exerted on the elastic portions to make the
elastic portions moving rearward. The contact moves downwardly under the
pressing force. The contacts may move out of the receiving passageways to
result a poor contact of the electrical connector. Thus, an electrical
connector with a baffled stick for restricting the contacts reversed is
desired to overcome the disadvantages of the related art.

[0005] Hence, the present invention is directed to solving this problem in
the related art.

SUMMARY OF THE INVENTION

[0006] An object of the invention is to provide an electrical connector
which has a baffled stick for restricting reverse of contacts therein.

[0007] In order to achieve the object set forth, an electrical connector
includes an insulative housing and a plurality of contacts secured in the
insulative housing. The insulative housing defines a mating face and a
plurality of receiving passageways running through the mating face for
receiving the contacts and arranged along a first direction thereof Each
contact defines a contacting portion protruding out of the receiving
passageway from the mating face. The electrical connector further
includes a baffled stick assembled in the mating face and across the
receiving passageways along the first direction of the insulating
housing.

[0008] Other objects, advantages and novel features of the invention will
become more apparent from the following detailed description when taken
in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0014] Reference will now be made in detail to the preferred embodiment of
the present invention.

[0015] Referring to FIGS. 1-5, an electrical connector 1 in accordance
with an embodiment of the present invention comprises an insulative
housing 10, a plurality of contacts 20 secured in the insulative housing
10, a pair of soldering pads 30 disposed at two sides of the insulative
housing 10 and a baffled stick 40 assembled in the insulative housing 10.

[0016] Referring to FIGS. 3 and 4, the insulative housing 10 defines a top
surface 101, a bottom surface 102 opposite to the top surface 101, a
mating surface 103 connecting with the top surface 101 and the bottom
surface 102 and a rear surface 104 opposite to the mating surface 103. A
plurality of receiving passageways 105 are arranged in a longitudinal
direction of the insulative housing 10 and extend through the mating
surface 103 and the bottom surface 102 for receiving the contacts 20. The
receiving passageway 105 defines a retaining slot 106 adjacent to the
rear surface 104 and extending in an up and down direction. The
insulative housing 10 further defines a retaining slot 107 recessed from
the mating face 103 and extending in the longitudinal direction thereof
The retaining slot 107 goes across the plurality of receiving passageways
105 for receiving the baffled stick 40. A pair of mounting slots 108 is
defined at two sides of the insulative housing 10 along the longitudinal
direction for retaining the pair of soldering pads 30. And a pair of
posts 109 is defined on two side ends of the bottom surface 102 along the
longitudinal direction. The insulative housing 10 is accurately mounted
on a printed circuit board (not shown) by the pair of posts 109 and the
pair of soldering pads 30.

[0017] Referring to FIGS. 3 and 4, each contact 20 is stamped from a
metallic plate and assembled in the insulative housing 10 from down to
up. Each contact 20 defines a flat retention portion 201 received in the
retaining slot 106 with interferential barb portions 202 at two lateral
sides of the retention portion 201 and engaged with the retaining slot
106. An elastic portion 203 bends downwardly from an upper end of the
retention portion 201 and is received in the receiving passageway 105. A
soldering portion 204 extends downwardly from a lower end of the
retention portion 201 and passing through the bottom surface 102 of the
insulative housing 10 after the soldering portion 204 is assembled in the
insulative housing 10. The soldering portion 204 is mounted to the
printed circuit board. A pair of contacting portions 205 is defined at a
distal end of the elastic portion 203 and protrudes out of the receiving
passageway 105 from the mating surface 103. The pair of contacting
portions is spaced and parallel to each other. The contact 20 defines a
restricting portion 206 extending from a distal end of the contacting
portion 205 and pressing against an inner face of the receiving
passageway 105 to provide a pre-compression for the contacting portions
205 of the contacts 20.

[0018] Referring to FIGS. 1 and 3, the pair of soldering pads 30 is
assembled in the mounting slots 108 at the two sides of the insulative
housing 10 from down to up. Each soldering pad 30 defines an up-standing
portion 301 interferential with the mounting slot 108 and a horizontal
portion 302 perpendicular to the up-standing portion 301 and used to be
sealed on the printed circuit board.

[0019] Referring to FIGS. 1-5, the baffled stick 40 is a lathy rectangle
and assembled on the mating surface 103. The baffled stick 40 defines a
top face 401 and a bottom face 402 opposite to the top face 401. A
plurality of engaging sections 403 are respectively defined on the top
face 401 and the bottom face 402 for retaining the baffled stick 40 in
the retaining slot 107. The retaining slot 107 defines a plurality of
retaining slits 100 corresponding to receive the engaging sections 403.
An inserting room 50 is defined among the part of the contacting portions
205 protruding out of the receiving passageways 105 and the mating
surface 103 (refer to FIG. 5). First, the baffled stick is inserted into
the inserting room 50 in the longitudinal direction and passes through
the contacting portions 205 of the contacts 20. Second, the baffled stick
is assembled in the retaining slot 107 from the mating surface 103 in a
lateral direction. Finally, the engaging portions 403 of the baffled
stick 40 are secured into the retaining slits 100 of the retaining slot
107. The baffled stick is coplanar with the mating surface. The baffled
stick 40 extends in the longitudinal direction perpendicular to a
direction in which the contacting portions 205 of the contacts 20 move.
The baffled stick 40 is located between the contacting portions 205 and
the elastic portions 203. When the electrical connector 1 mates with a
complementary connector (not shown), a pressing force is exerted on the
contacting portions 205 of the contacts 20, and then the contacting
portions 205 move into the receiving passageways 105 of the insulative
housing 10. The contacts 20 are also possible to move downwardly under
the pressing force. The baffled stick 40 prevents the contacts from
moving out of the receiving passageways 105 and improves an electrical
connecting performance of the electrical connector 1.

[0020] The present invention will now be described in detail with
reference to a preferred embodiments thereof as illustrated in the
accompanying drawings. In the following description, numerous specific
details are set forth in order to provide a thorough understanding of the
present invention. It will be apparent, however, to one skilled in the
art, that the present invention may be practiced without some or all of
these specific details. In other instances, well known process steps have
not been described in detail in order to not unnecessarily obscure the
present invention.
